Hello Lemonjello,
I have function tested the set up, yes. It worked so well around the furniture, I went straight to branch walking from one tree to another. Stropped to the second stem, I put a guestimate of slack into the system and retrieved the redirect and my splice. There was a snag, but the haul works well enough to break a branch. You don't want to lose your tail though.
They were 25m planes, so the distances were a good enough test for me. The result was being top anchored in one tree, stropped to the next, and free to progress with the other end of my line. Maybe not for everyday production climbing, but if you had a special TIP and a lot to get around, it might help. Or just a bit of fun on a social climb.
I salute your knuckles' sacrifice in the name of progress. I hadn't considered using gravity for the return, but I'll be setting your system up for sure, thank you.
The Shiny...the Shiny...
Depending on the friction, it works with a sling, three regular biners and any little shackle in your bag. Much more economical.
There's a deluxe adjustable version involving a MultiSAVER and a Wichard snap. Just squeeze the Revolvers onto the rings and splice a short tether for the snap.
Best regards,
Syd
